BACKGROUND

The approaches described in this section could be pursued but are not necessarily approaches that have previously been conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.

Since the early days of its inception, blockchain based networks have held a pseudonymous nature of identity that leads to a trustless network with the addition of ease and speed of global exchange. From Bitcoin to the other cryptocurrencies thereafter, these networks sometimes attract unsavory characters to partake in illicit purposes while using these cryptocurrencies as an exchange of value. Due to the desire to protect common users of these technologies, law enforcement, governments, and a handful of private companies have been on a quest to identify and trace the addresses used for illegal and illicit activities. Traditionally these efforts have been focused within the boundaries of their respective blockchain networks. Yet, as cryptographic transactions are now starting to branch blockchains with the rise of interoperability, there is a need to correlate different cryptographic addresses across multiple blockchain networks. Therefore, there is a need for correlating addresses in different networks controlled by the same entity as a way to trace value through multiple blockchain swaps, hops, and traversals.

Furthermore, the present technology serves as a way to trace value through multiple blockchain swaps, hops, and traversals in various embodiments.

In some embodiments, a majority of blockchain networks are composed of various cryptographic principles to ensure soundness, security, efficiency, and scalability. The foundation of these principles lies within the public and private key pairs that users hold and employ within a distributed network. Most users will use a specific key pair per network; however, this is not always the case. With the use of hierarchical deterministic wallet software, simplified payment verification, and the habitual use of common cryptographic elliptic curves, one can use the same key pair for multiple blockchains. In order to associate identifiable information across multiple blockchains, the present technology gains the respective cryptographic keys via exposed patterns that allows ascertaining of the necessary parameters for computing specific blockchain-based cryptographic address hashes. With the correlation of multiple cryptographic address hashes across multiple blockchains, the present technology enables tracing activity that travels through different networks and yet is still derived from a common cryptographic key pair. The common representation of an entity on a given blockchain is by their address hash. The address hash is derived via a cryptographic one-way hash function. The hash function follows a protocol by performing a function on a cryptographic public key. The public key may be used on multiple blockchain networks that use the same elliptic curve. Thus, any address generated from this public key has a connection to one or more addresses on any number of other blockchains that share this cryptographic key pattern. Using systems of the present technology, extraction of the public key is completed for any given address and computation of any number of address hashes that could be derived from the public key. By executing methods of the present technology, a correlation that an address on one network is synonymous with a given address on another network is made due to the mathematical principles of public key cryptography. Thus, systems of the present technology, over time build out a cross-blockchain network of addresses for a single entity that can lead to further clustering, associations and probabilistic determinations in various embodiments.

In some embodiments, the ownership and connection of an entity to a cryptocurrency asset or message is via cryptographic keys. More specifically asymmetric keys which yield a public and private key pair. The use of a public and private key pair enables a user or group of users to generate and manage funds tied to a multitude of derived address hashes.

In some embodiments, the generation of the keys themselves take place through a key-generation algorithm. Most blockchains and distributed cryptocurrency networks employ the use of elliptic curve multiplication to derive a public key from a private key and often they also use the same elliptic curve. Thus, a user (e.g., an entity) of one private key on a single blockchain could use the same key on a different blockchain network.

In some embodiments, with blockchains and distributed networks maturing, the exposure of these public keys is not as noticeable as a person of ordinary skill in the art may think. The common format of displaying public keys on blockchain networks is through cryptographic address hashes. In order to compute an address hash, the public key is put through a one-way cryptographic hash function and then encoded. However, at a deeper level, the protocol implementation exposes those public keys. Blockchains and distributed ledger-based networks usually encompass the act of transactional payments through two different models. These models are Unspent Transaction Output (UTXO) model and Account based model.

UTXO (Unspent Transaction Output) Model.

In some embodiments, for UTXO-model blockchains, transactions are linked together through their outputs. To ensure that transactions are valid, these networks utilize a scripting language to lock and unlock outputs to be spent. Every node on the network will validate transactions by executing these locking and unlocking scripts. Each input (i.e., spend) of a given cryptocurrency contains an unlocking script which refers to the previous UTXO. Each output (e.g., UTXO) contains a locking script. As a node verifies a transaction, the node takes both the locking and unlocking scripts and ensures that the unlocking script satisfies the locking scripts conditions. The evaluation and validation of the two scripts returns true if and only if the unlocking script has a valid signature from the private key of the recipient that corresponds to the hashed public key. Furthermore, the unlocking script contains the digital signature and public key. The digital signature itself proves that the owner of the private key used is the owner of the funds being spent, that the transaction cannot be modified, and that the proof of authorization is indisputable. Thus, with the corresponding public key exposed in a spend it can be guaranteed that the public key associated to the spend of a given address hash owns and controls the spend.

In various embodiments, with public keys being exposed in inputs for UTXO-model blockchains, the present technology enables relating hash160s exposed in corresponding outputs. There are some public keys in older outputs, however the most common parameter in outputs is a hash160. A hash160 is a cryptographic hash of a public key through the use of a one-way cryptographic hash function and cryptographic message digest which can be used by anyone to create a hash160 of a given public key. If all that is available is the hash160 and no public key, then one can take the cryptographic hash160 and extract the binary data. By adding a two-byte prefix, known as the version byte to the binary data, a cross-blockchain equivalent address representation may be generated. A human-readable address hash representation is created by applying a character-based encoding to this binary address.

Account Based Block Chain Model.

In some embodiments, for Account-based blockchains, transactions are not linked together through the spending of outputs. Account-based blockchains are similar to normal legacy banking accounts. A transaction in an account-based blockchain is nothing more than a sending/transfer of funds from one address to another. In addition to representing transactions differently, most address hashes are solely the last twenty bytes of the cryptographic one-way hash of the public key represented in a hexadecimal format. However, signing transactions are done the same way and usually with the same type of digital signature and elliptic curve as in UTXO-models. Signing transactions in Account-based model blockchains uses a digital signature generated from the keys and parameters established during the key-generation algorithm. The transaction contains three new parameters which can be used to recover the public key of the sender.

In some embodiments, the present technology in various embodiments consumes only five parameters that are used to build out a cross-blockchain correlation for a given address hash and/or public key. These parameters are Script Pattern, Public Key(s), Hash160, AddressHash, and Address Type.

In various embodiments, for UTXO-based networks, the present technology identifies the script pattern and extracts certain parameters when an address is either depositing funds or spending funds. These parameters include: one or more public keys itself, the corresponding hash160 for the address, the address hash, and address type. Note that present disclosure outlines that there may be one or more public keys. With the rise of privacy, some users may use multiple signature addresses which use multiple public keys to derive a single address. These addresses still fall in line with the implemented scripting language and are consumed by the present technology. If systems of the present technology consume the public key for a given address, then any possible address that is controlled by that key may be computed via the one-way cryptographic hash function supported by the given blockchain to generate addresses from public keys. If systems of the present technology consume the cryptographic hash160 of the address, the binary data is extracted to be used to compute any possible other address types across blockchains.

In various embodiments, for Account-based networks, the present technology derives public keys through a recovery mechanism when a given address hash is spending funds. Furthermore, with the systems described herein, the act of computing any possible other address types across blockchains consumes Account-based networks as well. By utilizing both UTXO-based and Account-based protocols at a given point, systems and methods of the present technology ascertain all five parameters (i.e., Script Pattern, Public Key(s), Hash160, AddressHash, and Address Type) for a given private key. Thus, over time, systems of the present technology may build cross-blockchain connections and clusters that associate users across any number of networks.

Examples of how the Present Technology May be Used.

In some embodiments, systems and methods of the present technology for correlating cryptographic address hashes between a plurality of blockchain networks may be deployed as a tool to associate cryptographic keys and cryptographic addresses across multiple blockchain based networks in real-time. By implementing systems and methods of the present technology across multiple blockchains, and then feeding the resulting computed data into a service, the present technology enables generation of an infinite number of cryptographic address hashes that have either been used on a blockchain already or will be used in the future. From this computed data, systems and methods of the present technology build out a network of cross-chain equivalents for entities. As blockchain technology iterates and becomes one of the forefront technologies used in the mainstream, systems and methods of the present technology may be used to combat exploitation, attacks, and illicit activity as the illicit activity jumps from one blockchain network to another blockchain network via new interoperability mechanisms and cross-chain swaps.

FIG. 3 is a block diagram 300 showing use of public key/private key pairs in association with blockchain specific address generation, according to exemplary embodiments of the present technology. The block diagram 300, shows a private key transformed to a public key using a mathematical transformation (“transform”). More generally, a transformation means a mathematical function. For example, a transformation may be an invertible function from a set X to itself, or from X to another set Y. The public key is transformed to a one-way derived cryptographic identifier using a one-way cryptographic transformation. The one-way derived cryptographic identifier is transformed to blockchain address hash using a heuristic address transformation, which is a blockchain specific address transformation. Examples of the transformations (e.g., functions) used in the block diagram 300 of FIG. 3 are shown below in table 400 of FIG. 4 .

FIG. 4 is a table 400 showing a representation of the transforms outlined in FIG. 3 for specific cryptocurrencies, according to exemplary embodiments of the present technology. For example, the mathematical transform Secp256k1 is used for cryptocurrencies Bitcoin, BitcoinCash, Litecoin, and the like, and is also used for cryptocurrencies Ethereum, Binance Chain, Rootstock, Cosmos, and the like. For example, Secp256k1 is the name of the elliptic curve used by Bitcoin to implement its public key cryptography. All points on this curve are valid Bitcoin public keys. When a user wishes to generate a public key using their private key, they multiply their private key, a large number, by the Generator Point, a defined point on the Secp256k1 curve. Thanks to the Discrete Log Problem, dividing a public key by the Generator Point cannot yield a private key. For example, the one-way cryptographic transformation RIPEMD-160(SHA256(PublicKey)) is used for cryptocurrencies Bitcoin, BitcoinCash, Litecoin, and the like. Furthermore, the one-way cryptographic transformation Keccak256 Hash(PublicKey) is used for cryptocurrencies Ethereum, Binance Chain, Rootstock, Cosmos, and the like. For example, the heuristic address transformation Base58Encode(VersionByte+OneWay-Result) is used for cryptocurrencies Bitcoin, BitcoinCash, Litecoin, and the like. Furthermore, the heuristic address transformation subtract last N bytes is used for cryptocurrencies Ethereum, Binance Chain, Rootstock, Cosmos, and the like.

FIG. 5 is a block diagram 500 showing Unspent Transaction Output (UTXO) model-based blockchain address generation, according to exemplary embodiments of the present technology. The block diagram 500 shows blockchain address generation using the Unspent Transaction Output (UTXO) model. The public keys proceeds to the one-way cryptographic hash function. The one-way cryptographic hash function proceeds to the cryptographic message digest. The result of this is the Hash160. For example, the Hash160 class provides methods for hashing data first with SHA-256 and feeding that result into the RIPEMD-160 hash. The cryptographic message digest proceed to the public key hash. The public key hash proceeds to the encoding with version byte. The encoding with version byte proceeds with the blockchain address generation.

The block diagram 600 shows blockchain address generation using the account-based model. For example, public key proceed to the one-way cryptographic hash function. The one-way cryptographic hash function proceeds to the blockchain address generation by taking the last N bytes of the hash in various embodiments.

The block diagram 800 shows Sender's Public Key by abstraction. Transaction object proceeds to a raw unsigned transaction message by re-generating raw transaction object with unsigned parameters including (v, r, s). The Raw unsigned transaction message proceeds to the Serialized transaction object based on (v, r, s) using the serial un-singed transaction object. The Serialized transaction object based on (v, r, s) proceeds to the sender's Public Key using the elliptic curve digital signature transform.

FIG. 11 is a diagrammatic representation of an example machine in the form of a computer system 1, within which a set of instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In various example embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines.

While this technology is susceptible of embodiments in many different forms, there is shown in the drawings and has been described in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the technology and is not intended to limit the technology to the embodiments illustrated.

Although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not necessarily be limited by such terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be necessarily limiting of the disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes” and/or “comprising,” “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Example embodiments of the present disclosure are described herein with reference to illustrations of idealized embodiments (and intermediate structures) of the present disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the example embodiments of the present disclosure should not be construed as necessarily limited to the particular shapes of regions illustrated herein, but are to include deviations in shapes that result, for example, from manufacturing.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized and/or overly formal sense unless expressly so defined herein.

Furthermore, relative terms such as “below,” “lower,” “above,” and “upper” may be used herein to describe one element's relationship to another element as illustrated in the accompanying drawings. Such relative terms are intended to encompass different orientations of illustrated technologies in addition to the orientation depicted in the accompanying drawings. For example, if a device in the accompanying drawings is turned over, then the elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. Therefore, the example terms “below” and “lower” can, therefore, encompass both an orientation of above and below.

The description of the present disclosure has been presented for purposes of illustration and description but is not intended to be exhaustive or limited to the present disclosure in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the present disclosure. Exemplary embodiments were chosen and described in order to best explain the principles of the present disclosure and its practical application, and to enable others of ordinary skill in the art to understand the present disclosure for various embodiments with various modifications as are suited to the particular use contemplated.

While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. The descriptions are not intended to limit the scope of the technology to the particular forms set forth herein. Thus, the breadth and scope of a preferred embodiment should not be limited by any of the above-described exemplary embodiments. It should be understood that the above description is illustrative and not restrictive. To the contrary, the present descriptions are intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the technology as defined by the appended claims and otherwise appreciated by one of ordinary skill in the art. The scope of the technology should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the appended claims along with their full scope of equivalents.
